Recent U.S. Drought Monitor data through August 18, 2026, show exceptional (D4) drought covering 1.1% of the contiguous United States, concentrated in western Nebraska, parts of Colorado, northeastern Oregon, and southern Idaho amid persistent heat and below-normal monsoon rainfall in the Intermountain West. The National Drought Mitigation Center and partners assess D4 using multiple indicators including soil moisture, streamflow, and vegetation health, with degradation noted in the Southern Plains and Far West while heavy Midwest rains produced localized improvements. The next USDM map, released around August 27 and valid for the week of August 25, will reflect conditions through late August; National Weather Service outlooks favor below-normal precipitation across much of the West and South through early September, sustaining the primary driver of limited D4 persistence in a handful of western states.
